Thomas & Mary (Crotty) Meagher reputedly had three sons. We know that Thomas, Jr, and Henry were partners in the family business at Waterford. Gen. Thomas Francis Meagher was the son of Thomas, Jr.
I am researching my grandfather James Joseph Meagher/Maher born in Newfoundland late 19th century, emigrated to Cambridge, MA, early 20th century and died in Waltham, MA, 1965. Missing a Newfoundland link to Thomas, Sr, that might be that third son — any information?
